Experimental synchronization of threshold coupled chaotic oscillators

In this paper, a new method of achieving anticipatory and complete synchronization through threshold coupling of two threshold controllers based chaotic oscillators is proposed. Until now, most of the synchronization of chaotic systems stated in the literature are based on common coupling methods like unidirectional and bidirectional coupling but rarely, cascaded and delay coupling. In this direction to add on a new kind of coupling known as threshold coupling is employed in this work. This coupled systems exhibit complete (CS) and anticipatory synchronizations (AS) for decreasing coupling resistor value without parameter mismatch and delay line. The proposed circuit is investigated experimentally and circuit behavior is also simulated using Multisim.
